LED Adaptor - 7 Pin Flat Socket to 7 Pin Small Round Plug

The LED Plug has been designed with a unique in-built LED circuit tester designed to detect errors in the circuit at the trailer plug for electric brakes, auxiliary (emergency) break light system, indicators, park lights and brakes.

The LED Trailer Plug ensures safe towing by providing an accurate visual-check, via six illuminated LED's, which light up to indicate enough power is supplied through each correct circuit and that the power from the source is active through the trailer plug.

In the round 7 pin small and large trailer plugs and sockets, the KT Plug now incorporates a revolutionary 3 step wiring body which makes installation as simple as a 7 pin flat plug.

The LED wiring from the circuit board to the LED’s has wire connections that are standard industry colours to assist the DIY or DIFM customer easy installation.
